I saw these at the Costco in Orland Park, IL and could not pass them up. Got (2) 4-packs and note you pay tax on the full cost, not the after rebate cost. They also had the 100w CFL's for 7.99 with a 4.00 instant rebate making them 3.99 for a 4-pack. Still pretty cheap, so I bought 2 of these also.

I originally went looking for the Eneloop 10 battery deal for 19.99, but they only had the (8) AA + (4) AAA + Charger for 25.99 - 5.00 instant rebate. It's a pretty horrible charger, so I passed this deal up. Was looking for the AAA deal, but they no longer had them.

I bought a few cases of Feit CFL globe style and flood light style bulbs at Costco Sacramento a few months ago. 4 in each box and there was a $10 rebate off of the $10.99 price. As weigel2 stated, there was tax on the pre-rebate price. So, I think I spent roughly $2 on each package and sold them on Craigslist for $8/box.

FIAT BULBS TAKE FOREVER TO "WARM UP". I would stay away from them. You turn them on and they are dim. Several minutes later you have full light. Do yourself a favor, many GE's warm up almost instantly.
